Iron in fill water & iron stains

[Dennis in Minnesota]

I am required to keep our commercial pools at 3 to 5ppm chlorine. I don't think the Minnesota state pool inspector would accept anything lower. Also I have 3ppm iron in my drilled well water, and have problems with bad staining in the pools.

I am thinking of putting in a non softening iron filter system. Is it worth the money, or should I just use chemicals to fight it?

One more question. One pool is badly stained now, I have to drain it this spring before we open to do some warranty work on it. Should I try to use chemicals to clean it before I drain it, or drain it and acid wash it? Thank you for your time and any suggestions that you have.

Acid washing is always the cheaper and easier fo the two you mentioned.

You see stains in pool and discoloration due to Fe1 changing to Fe 2 you can reduce the pH levels to hold Fe in water.

Though i would recommend you have water pretreated if the Fe levels are that high from your feed.
